Take a careful look at the center of a cauliflower and notice how the florets spiral. Each spiral begins in the center and moves outward. Some florets spiral clockwise, and some spiral counterclockwise. Fibonacci numbers show up in the spirals of the cauliflower.

a. How many spirals extend from the center in a clockwise curve? Is it a Fibonacci number?

b. How many spirals extend from the center in a counterclockwise curve? Is it a Fibonacci number?
